House calls for heat pump repair can start piling up through the years. Your heat pump is the most used electronic device you have in your home. You use it for air conditioning when the weather is warm and for heating when it’s cold outside. Taking this into consideration, it might be useful to invest some of your time into learning how to do basic troubleshooting on your heat pump.
Step 1 – Observe for Signs of Malfunction
You need your powers of observation to diagnose the problem plaguing your heat pump. Is your heat pump too hot or too cold? Does your heat pump refuse to start?
Step 2 – Diagnose the Problem
When your pump fails to run, first check the fuses and the breakers. It might be an electrical error rather than a machine one. Newer models usually have a reset button on their heat pumps. If your pump has one, you can try pressing the reset in a bid to have everything working back to normal. Short cycles may be brought about by the outdoor coil accumulating too much debris. Try removing any debris left on your outdoor coil and see if that works.
Check to see if you have the same temperature all throughout the entire house. If other rooms are colder or warmer than the others, you may have to balance your forced-air distribution system.
Another thing to be wary about is the defrosting mechanism on your heat pump. Defrost cycles should not last for more than 15 minutes nor should more than one defrost cycle happen in 1 hour.
Restarting your heat pump is required if the device refuses to run for more than an hour and the temperature is below 50 degrees F.
Step 3 - Clean or Replace the Filter
You can remove the filter either by sliding or unwrapping through the blower access door located on the outdoor unit. Once you have the filter out, clean the entire area either by vacuum or by wiping the surface with a damp cloth. If you feel that there’s too much grime on the filter that you can’t remove much of it anymore, you can opt to just replace it with a new filter.
Step 4 – Oil and Adjust the Unit
Look for lubrication ports or holes that have the word oil near them. There are usually lubrication ports near motors and pulleys. Once you’ve found them, use light lubricating oil on the holes. Some heat pumps have a belt drive although other units may not have any. If your heat pump has one, loosen it but not to the point that it just slips down. Replace the belt if it looks too worn out. Check the mounting bolts on your unit and tighten those that do not fit snuggly anymore.
Step 5 - Restart the Unit
Look for the system selector switch on your heat pump and set it to emergency heat. Keep the setting for up to 6 hours and then set the unit back to normal heat setting.
